Ontario Bill 40

Ontario Bill 40 has been enacted.

Enacted December 11, 2025, this law amends the Electricity Act and Ontario Energy Board Act to embed economic growth as a formal regulatory objective and grants the Minister of Energy and Mines new authority to approve and prioritize large data centre grid connections based on economic, strategic, and community benefit criteria. It ends the prior first-come, first-served connection regime for high-demand facilities and restricts foreign participation in Ontario's energy sector.
